This paper draws upon the theory of embodied cognition to provide a robust account of how gestural interactions with and around multi-touch tabletops can play an important role in facilitating collaborative meaning-making, particularly in the context of science data visualizations. Embodied cognition is a theory of learning that implies that…

Molecular symmetry and orbitals are two important chemical concepts which can be difficult for students to visualize in three dimensions; as such, instructors have traditionally adopted a variety of approaches to teach them including the use of physical models and digital renderings/resources. This paper describes a new mobile device application…

The Museum of Science and Industry (Chicago) has created a new exhibit, "Technology: Chance or Choice?," which emphasizes the human impact on technology. Development of and techniques used in the exhibit are discussed. The latter include microcomputers placed throughout the exhibit to pose questions about critical issues raised by particular…

Describes the use of an Energy-Environment Simulator in environmental/energy education programs. The simulator is a specially designed analog computer that simulates real-world conditions of energy production and use. Energy resources, demands, and the environmental effects of energy use are programmed into the computer. (Author/JN)
